"Ultimately it's the games that make Xbox One stand out, and we have the best lineup of games--we think--in the history of consoles," Harrison said.
Launch titles for the Xbox One include big-budget and high-profile games like Call of Duty: Ghosts and Battlefield 4, as well as free-to-play fighting game Killer Instinct and various sports titles like Madden NFL 25, NBA Live 14, and FIFA 14.
In Europe, FIFA 14 will be included as a free pack-in game for all Xbox One preorders.
"We clearly have strong exclusive games, and we have partnered with EA to bring FIFA to Europe in a very meaningful way. Football in Europe is the sport, and in some countries it's the religion," Harrison said.
The Xbox One launches in November for $500.
